IMPRVEMENT IN nEER-FAUCETS.

Thaseheduvle referrel'to in these Letters Patent and making part. of the same Toall 'whom 'it may concern ,i t

Be` itknown that I, THEQDORE AH1tnNs,`of Louisville, in the county of Jefferson and vState of Ken.-

tucky, have `invented certain new and useful Improvements in` Beer-Faucets and 1' do hereby declare that the following 'is a full, clear, and exact description thereof, reference being had tothe accompanying .drawings and to the letters of deference marked thereon, which forma part of this specification.

`'.lhe `nature of my 1 invention consists in the construction andaITangement-of a beer-faucet, as will be hereinafter fully set forth.

In 'order to enable others skilled in the artA to which my invention appertains to make and use the same,

`I will now proceed to describe its construction and operation, referringxto 'the annexed drawings, which representI a longitudinalrvertical section of my falcet.

A represents the maintnbe, provided with a strainer on 'the inner end,\to be inserted inthe beer-barrel.

In the outer end` is the usual cylinder B, provided with an aperture and alever, G, for turning the beer.-

off or on at will.'

Inside of the cylinder B, is a tube, D, leaving a space `or chamberbetween. its outer side and the inner side of the cylinder', for lthe beer to-flow through.

This tube is provided with a small aperture, facing the lower edge of the aperture in the cylinder, and its lower end is provdedwith a nl 1t,E,haviuga tine hole through its centen Inside of the-tube Diis avalre and valve-stern, G,

- which is movedup and down by the turning of the Y lever O iu the following manner: i

In the vupper end of the valve-stemG is a pin, a, which projects through a spiral slot` in the tube D,

and enters aspiral groove'in that portion of the cylinder B ofthe faucet through which the cylinder passes, so that thus, by thev turning of the lever Gand tube vD, the'valve-stem is moved up and down.

The faucet isso arranged thatit requires but a quarter-turn of the lever to make the'be'er flow and squirt.

By turning the faucet. on, the beer flows between `the tube D and cylinder B; by turning it off, the beer in the tube D is squirted outby the valve G, through hole in the not Il; which produces the foam or steam as it is'called. l

In ,the main body A of the faucet is ahah-passage,

H, `having an upright, conductor, I, which, by a rubber or otheriiexible tube, is connected with the bung.

ThisA air-passage is so constructed as to be closed when the faucet -is turned off," butI open when the faucet is turned on, so as to conduct air `into the barrel while th'e beer is flowing, and that just enough to lill the vac-num caused by the outflow, the benefit of which is'that `it keeps the properties of Vthe .beer condensed in their proper limits, so that the last glass let out is asgood as the first.

, Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, .is-

The combination of the cylinder B, tube 1), 'nut E,-
